55 day Go

Learning journey with Go programming language - the "Golang" with "gopher" mascot.

Some tips for beginners/novices as a "cheat sheet" to learn quicker. Mostly language features & stdlib up to Golang 1.18 release (2022 Mar), though 1.20+ is recommended.

Usage

Basic Usage

Build and run (given setup already done $GOPATH $GOROOT etcetera) in each folder (e.g. src/0-hl):

  $ cd src; cd 0-hl
  $ go run .

Usually there is one .txt file in each folder in "src" directory, which includes the steps to build and run. And it even contains the sample output of each instruction/command (mostly)!

Samples

  $ cd ../hello
  $ go build hello.go

When BUILD OK (no error in standard output/console), we can proceed to running and testing.

Running samples

  $ ./hello
  $ go run hello.go
  $ go run .
  $ cd ../greetings
  $ go test example.com/greetings
  $ go test . -v --count=1

Likewise, you can run "4-slices" or "5-range", it's up to you!
